It's just the way of the world, that without hardware, any program on Smart Phones and Tablets can not influence the reality. As you have already read about MyApps for Control of Model Railway, you know those it use the Arduino platform to control train models and layout devices. To connect details of Arduino with each other using a Breadboard and wires it is possible, but it is very inconvenient and unreliable. And to avoid this, I came up with a USB board.
This board uses Arduino NANO. Therefore, the dimensions of URBs are only 65x75 mm, which makes it possible to hide it even inside model building. This solution provides excellent flexibility, maintainability, simple mass production and low cost. The board is designed to avoid incorrect connection of Bluetooth modules and Arduino NANO.To the functions of Arduino, the board (URB unit) adds the following capability:
